<div>Looking forward to hearing your results of using it, in the
car. What is the original seal material made of? It's not
metallic, and feels like plastic or really hard rubber. I was
thinking using valve lapping paste could recondition the mating
surfaces that isn't too far gone?</div>

<div>That is awesome. Is that a pool pump seal? Mine is the
first one I ever pulled apart, but I assume the other inner seal is
simply to contain the bearing grease. Since you are using sealed
bearings, did you still use that seal?</div>

<div>
<div>After a couple of premature failures of repro 100
water pumps I decided to look into rebuilding them with a modern
seal and sealed bearings.
<div>I have some concerns about the small size of the
annulus through which all the coolant must pass in the original
design so I have managed to install a considerably smaller seal as
in the pics attached. </div>
<div>After bench testing one of the prototypes is now
fitted to my car awaiting a test drive as soon as the snow is
gone.</div>

<div>What's the skinny on the repo 100 water pumps? Hear they leak
and need broken in dry. Uprated pump any good? Moss states the
brass tap can be screwed into the uprated pump, but from the
pictures it actually looks like the standard has threads and not
the uprated. Can anyone confirm? Rebuild original?Thoughts/ advice
welcomed?</div>
